a specification.

This invention relates to axles, and has referencemore particularly tothe wheel-carrying s indles, the invention being peculiarly applica leto that form of spindle constructed from a flanged bar, in which theflanges are n rounded to present curved bearing-surfaces,

leaving longitudinal s aces between the inner 'faces of the roundedanges and the body of the spindle.

In certain types of spindles of this form the rounded bearing surfacesformed conjointly by the flanges are not continuous, being interruptedwhere the edges of lthe flanges terminate, and it has been the practicein order to afford a continuous uniform *bearing for the wheel-hub toapply to lthe spindle a bearing or wear collar. This practice, however,is objectionable for many.

reasons, mainly on account of the'expense involved.

My invention is designed to avoid this objection and it consists in aplying in the longitudinal spaces between tlie rounded flanges and thebody ofthe spindle filling blocks or 'members shaped exteriorly toconform to the general rounded curvature of the flanges,

. so that a continuous uniform cylindrical bearing-surface is presented,to which the wheel may be directly applied without the intervention of abearing-collar. l

I prefer to form the filling-blocks of wood Y" Hor other fibrousmaterial in order to ada t them to retain the lubricant to a properegree and'to distribute the same'effectively to the bearing-surfaces.

The invention consists also in the details of construction andcombination of partshereof an axle and its bearing-spindle having myv finvention'embodied therein and showing the Vwheel-hub applied thereto.

Fig. 2 isla vercal transverse section on the linea a of the precedingfigure. Fig. 3 is a similar view on the line l) b. Fig. 4 lis a similarview on' the line c c. Fig. 5 is a transverse'sectionshowing mylinvention embodied in a spindle ,of

slightly different form.

'Referrin" Vto the drawings, 1 represents the body o an axle, 2 thewheel-spindle, and 3 the wheel-hub mounted thereon. In the presentinstance the axle consists of a flanged ar of I form in cross-section,the s in dle being integral therewith andformed yrounding the flanges atthe end of the bar, producing` an upper curved bearing-surface 4, formedby the up er flanges, and a lower curved bearing-sur ace 5, formed bythe lower flanges, which bearing-surfaces are interrupted where theedges of the flanges terminate, this construction leaving longitudinalspaces 6 and 7 between the inner faces of the round- .ed flanges and thebody of the spindle, in

the lpresent instance the central connectingweb 8. In applying myinvention to a s indle of this form I insert in each of theseongitudinal spaces alongitu'dinal filling block or member 9, of wood orotherfibrous material and vof a cross-sectional form,`which will snuglyand tightly fit said spaces, the fillingblock having an inner flat side9a, whichbears along the side-of the web 8; upper and lowercurved'surfaces 9b, which bear at the'inner faces of the upper andlowery flanges outwardly-extending upper and lower shoulders 9C, whichextend along the edges of the flanges, v

It is seen, there-- without the necessity of providingan interv Y,

mediate bearing-collar.

At their 'nner ends the filling-blocks extend beyond thespindle and fora short distance along the web of the axle, towhich web they arefastened bya bolt 10, extending- At their outer ends-the y throughsaidparts. filling-blocks terminate a short. distancev inward .of theextremity of the spindle, to which'is applied a cap 11, formedinteriorly to snugly lit the upper and lower bearingn surfaces 4 and 5,whlchcap is provided on its interiorwith ribs 11a, Fig. 3, extendinginward and fitting between the edges of the 'roo curved flanges of thespindle. This cap is held in place by a bolt 12, extending through theribs and the web of the spindle and confined by the cotter-pin 13.

It will be observed that the access of dust or sand to thebearing-surfaces is effectually prevented at the inner end of thespindle by the filling-blocks and at the outer end by the cap l1, theinner end of which extends beneath the outer end of the hub, thusforming an effectual seal. From the continued application of thelubricant the fibrous fillingblocls become saturated with the same, andby contact directly with the hub-bearing surface it is evenly anduniformly distributed in the proper quantities for effectivelubrication.`

If desired, a longitudinal groove 9e may be formed in the outer curvedside of the fillingblocl to form a reservoir for the lubricant.

While I have shown my invention applied to a spindle formed from a barof I form in cross-section, it is manifest that the invention isapplicable as well to spindles formed from bars of other cross-sectionalformssuch, for instance, as a bar of Z form, as shown in Fig. 5,comprising a central connecting-web and two oppositely-extendingangularly-disposed flanges. It is obvious also that the invention isapplicable to spindles formed from a flanged structure built up of laminof metal sheets.

Having thus described my invention, what I claim is- 1. In combinationwith a metallic bearingspindle comprising a web and integral roun edflanges with longitudinal spaces between the flanges and the web,independent fillingblocks of fibrous material extending, one at eachside of the web in the longitudinal space between the flanges and theweb, said blocks having their outer surfaces formed to constitute acontinuation of the bearing-surface of the flanges, and means formaintaining 'said blocks fixedly in place.

2. In combination with a metallic axlebody comprising a web and integrallongitudinal flanges, a wheel-bearing spindle forming an integralcontinuation of the body, and comprising a web and curved flangesconstituting the wheel supporting and bearing surface, and independentfilling-blocks of wood, seated on'opposite sides of the webrespectively, in the longitudinal space between the flanges and web,said blocks having their outer surface curved to form a continuation ofthe'bearing-surface of the flanges, and a fastening device securing theinner ends of the filling-blocks fixedly to the web of the body portion.

3. In combination with a metallic axlebody of I form in cross-section,an integral bearing-spindle comprising op] )ositely-disposed curvedflanges constituting the bearing-surface of the spindle, and a centralweb connecting said flanges, filling-blocks of fibrous material seatedin the longitudinal spaces at the opposite sides of the web, and havingtheir inner ends terminating beyond the inner ends of the spindle, saidfillingblocks having an inner flat side bearing against the side of theweb, upper and lower curved surfaces bearing against the inner faces ofthe flanges, and outer curved sides forming a continuation of thebearing-surface of the flanges, and a fastening device scouring theinner end of the blocks firmly to the web of the axle-body.

4. In combination with a metallic axlespindle comprising rounded flangesand a connecting-web with longitudinal spaces between the inner faces ofsaid flanges and the web, independent fibrous filling-blocks extendingin said spaces and having their outer sides formed exteriorly toconstitute continuations of the bearing-surface of the flanges, andmeans for securing said blocks fixedly in place.

5. In combination with an axle-spindle comprising rounded flanges, witha space between the edges of the flanges, a wheel mounted on thespindle, a confining-ca 3 applied to the end of the spindle and formewith an inwardly-extending shoulder fitting between the edges of theflanges, and a fastening device securing the cap to the spindle.

6. In combination with an axle-spindle comprising rounded flangesoppositely disposed, with spaces on opposite sides of the spindle,between the edges of the flanges, a wheel applied to said spindle, aconfining-cap on the end ofthe spindle, shoulders on the inner surfaceof the cap at opposite sides, extending between the edges of theflanges, and a fastening-pin extending through the capshoulders andspindle, and serving to fasten the cap on the spindle.

In testimony whereof I hereunto set my hand, this 22d day of August,1905, in the presence of two attesting witnesses.
